The analysis of the turbogenerators’ TВВ-1000-2Y3 failure has shown that the most vulnerable link in the stator is such of their elements as tightening prisms, the teeth of the end packet core, lead-out and connecting buses of the stator winding. The basic reason for the destruction of the elements...
